Garage door tracks come galvanized for protection against rust and corrosion. Earlier tracks had raw steel simply

covered with black paint. Vertical track lengths range most commonly from six feet four inches up through 14 feet and four inches,

and mostly in 12 inch graduations.
Garage door tracks can be purchased in three widths, one, two and three inch. One-inch tracks find most common use in truck

and semi-trailer door applications. Two-inch tracks comprise most residential and commercial applications. Three-inch tracks

support and guide heavier residential and industrial garage doors.
Residential tracks commonly measure 0.055, .062 and .075 inch in thickness. Over the years, tracks have seen a reduction in thickness,

for the many lighter steel doors in use. The standard thickness for heavy wood doors was 0.075 inch. Prior to that the track standard came

in at 0.083 inch. Three inch tracks are normally constructed with 0 .109 inch steel.
